ArcGIS and Archaeology: Practical Tutorials for the Use of ArcGIS in Archaeology is a cool site I ran across last week. Born out of the need to use GIS for research and the want to help other archaeologists who may be put into the GIS chair, this site provides background info on both GIS and ESRI ArcGIS products. Further, this site has a small collection of tutorials for some more common GIS/Archaeology applications, such as, creating contour lines, terrain modeling, and viewsheds. A nice looking site with a cool idea; I hope the author continues to add to the tutorial collection.
As a side note, I found this site with going through the large number of links at: Archaeological Research Resources. This is, courtesy of Historic Archaeological Research, has a ton of links for many aspects of archaeology, both research and field.
